The Trail Blazers hosted four second-round hopefuls in a predraft workout Friday at the practice facility in Tualatin as their draft evaluating enters the home stretch.

Although each player is considered a "bubble" prospect, the group did feature two college National Champions, the NCAA's most prolific scorer and a French prospect with years of international experience.

Here's a closer look at the four prospects, including a brief scouting report from Chad Buchanan, the Blazers' director of college scouting.

Jon ScheyerVitals: 6-foot-5, 190 pounds, guard, DukeNotable: Finished four-year Duke career as the only player in school history to register at least 2,000 points, 500 rebounds, 400 assists, 250 three-pointers and 200 steals. ... His 2,077 career points rank ninth all-time in Duke history. ... He also finished in the top 11 in three-pointers made (fourth, 297), steals (eighth, 208), free throws made (third, 608) and assists (11th, 440). ... Was a Second-Team AP All-American and a First-Team All-ACC selection as a senior, when he averaged 18.2 points and 4.9 assists and led Duke to a National Championship. Buck’s take: "He's big, has good size for a perimeter guy. He lacks a little bit athletically and quickness-wise. But a very intelligent player. Proved this year that he can run a team (but) I think at our level he's going to play off the ball. He's got to prove that he can guard quickness and he's probably going to have to become a better catch-and-shoot guy. I think he's a decent catch-and-shoot guy, but not like a knock-down guy yet. But his size and his smarts are something that will carry him for a while here. He's just got to prove that the athletic part is something that he can overcome."Links:DraftExpress page.Wikipedia.

Deon ThompsonVitals: 6-foot-9, 245 pounds, forward, North CarolinaNotable: Set NCAA record for most games played in college career (152). ... Averaged 13.7 points and 6.7 rebounds last season as a senior, when he ranked fifth in the ACC in field goal shooting (48.4 percent). ... Averaged 10.6 points and 5.7 rebounds as a starter on North Carolina's National Championship team as a junior. ... Played for Team USA in the summer of 2007 at the U-19 World Championships in Serbia, where he averaged 10.0 points and led the team in rebounding (6.1 per game). Buck’s take: "Solid four-year guy from, obviously, a fantastic program and fantastic coach. I think he's a guy who's waiting to take the next step in his game. He's got to prove that he's willing to play physical around the (basket). He can step out and shoot it. Mid-range jumper is probably the strength of his offensive game. But I think he's got to become more committed to rebounding the ball and defending. But he's got decent size and (he's a) decent athlete. Good footwork. He's a guy who's on the bubble of being drafted. He and Jon are probably in that same boat."Links:DraftExpress page.NBADraft.net page.North Carolina bio page.Wikipedia.

Aubrey ColemanVitals: 6-foot-4, 20 pounds, guard, HoustonNotable: Led the NCAA in scoring as a senior, when he averaged 25.6 points per game. ... Was a First-Team All-Conference USA selection as both a junior and senior at Houston after transferring from Southwest Mississippi Community College. ... Led Houston in scoring, rebounding (7.4 per game) and steals (2.7) and ranked second in assists (2.6) as a senior. ... Scored 20 or more points in 29 of 35 games and scored 30 or more points nine times last season. Buck’s take: "He was on his fourth consecutive day of workouts ... but I thought he was sharp today. One of the best scoring guards in the country. He led the nation in scoring this year. Played for kind of a free-wheeling offense, where he kind of had the green light to do a lot of things. Surprisingly not a great perimeter shooter, but he knows how to put the ball in the hole. Little small for a two, but it's hard to argue with what he did this season. I think he's probably a guy who's a late-second round (pick) or undrafted (pickup). But a guy who scored like that, somebody will give him an opportunity at some point."Links:DraftExpress page.Houston bio page.NBADraft.net page.

Ludovic VatyVitals: 6-foot-9, 240 pounds, forward, FranceNotable: Has played club basketball in France since age 11. ... Competed at the French National Institute of Sports and Physical Education — where Tony Parker and Boris Diaw played — from 2003-06. ... After playing three seasons for Pau-Orthez, signed with Entente Orleans 45 last season and averaged 8.0 points and 4.9 rebounds. ... Has played for Team France internationally at the U-16, U-18, U-20 and Senior National Team levels.Buck’s take: "We've seen him for quite a few years now. Saw him over at the EuroCamp about 10 days ago. Physical, below-the-rim player for the most part. Has good footwork and good hands. (Athleticism) is something that he'll have to overcome to a certain degree. I think he could be a very high level European player, possible a second-round pick for somebody to maybe stash overseas. But he's got a good feel and has a lot of experience at a high level over there."Links:DraftExpress page.NBADraft.net page.
